[PATCH 17/50] drm: kill the ->agp_destroy callback

[Daniel Vetter]

Call drm_pci_agp_destroy directly, there's no point in the
indirection. Long term we want to shuffle this into each driver's
unload logic, but that needs cleared-up drm lifetime rules first.

v2: Add a dummy function for !CONFIG_PCI, spotted my David Herrmann.

v3: Fixup for the coding style police.
